* MACHINE FOR CRACKING- OFF GLASS ARTICLES.

Specification of Letters Patent.

Patented July 9, 1907.

Application filed February 8,1907 Serial No- 356,372-

To all whom it may concern.-

Be it known that I, CHRISTIAN Aunusnn, of Cicero,

county of Hamilton, and State of Indiana, have in vented a certain new and useful Machine for Cracking Off Glass Articles; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, in which like letters refer to like parts.

The object of this invention is to mechanically sever or crack off tubular and like glass articles, especially by electricity.

The machine was invented and is designed for cutting very long glass tubes into sections, and it is so constructed and operates in such manner that this object is quickly and easily accomplished without loss from breaking or injury to the glass. 1

The features of invention consist in the means for holding the glass article and in means for applying electricity thereto for severing the same, and in the combination of the said two kinds of means.

The nature of the invention will be understood. from the accompanying drawings and the following description and claims.

ln the drawings Figure 1 is an elevation of the righthand side of the entire machine. of the machine. Fig. 3 is a vertical transverse section on the line 33 of Fig. 2 looking rearward, but the dynamo being broken away. Fig. 4 is an elevation of the left-hand end of the glass holder and cutter, showing the electric heating wires in contact with the glass. Fig. 5 is the same with the electric heating wires removed from the glass. Fig. 6 is a horizontal section on Fig. 7 is a section on the line 7-7 of Fig. 2.

A suitable base 10 is provided on which two wide 13 and 14 on their upper ends and integral therewith in which a glass-holding cylinder 15 is revolubly mounted. Said cylinder has on it a large gear 16 for revolving it, and that gear is driven by a pinion 17 on the shaft 18 mounted behind the posts 11 and 12, as seen in Figs. 1 and 2, and upon posts 19 and 20. The

shaft 18 carries a large gear 21 that is driven by a pinion 22 on a shaft 23 of a motor 24. 1t is observed that this train of gearing is arranged so that the speed of the glass-holding cylinder 15 will be relatively much slower than that of the motor shaft.

The cylinder 15 is held from longitudinal movement by washers 25, 26, 27, and 28 that are placed beside the bearings 13 and 14 on the posts 11 and 12, and the gear 16 is secured to said cylinder bya set screw 29. On the right-hand end of the cylinder .15 a sleeve 30 fitsloosely and is held from rotation by a screw 31 on a bracket 32 which is fastened to the post 12. This sleeve 39 extends beyond the end of the cylinder 15 and has on it a radial outwardly extending flange 33 Fig. 2 is a plan view that has at equidistant points radial slots 34 through which pins 35 extend that carry arms 36 having beveled heads 37 which engage and hold the tube of glass 38. The pins 35 project through eccentric or cam-like slots 40 in an annular disk 41 mounted on the cylinder 15 immediately to the left of the flange 33 so that when said disk 41 is oscillated somewhat, the glass holders 37 will be moved into or out of engagement with the glass tube. There are three of these glass holders, and the disk 41 is oscillated by a hand lever 42 fulcrumed at 43 on the lower end of the bracket 32 and rigidly mounted on a crank-shaft 142 that has a pin 143 extending through the slot 144 in the bell-crank lever 44 which is fulcrumed' at 145. The upper portion of said bellcrank lever 44 has at its upper end a slot 45 through which a screw passes and is secured to said disk.

The means for cracking-off or severing the glass tube is located at the left-hand, as appears in Fig. 3. As there shown, a sleeve 50 is rigidly mounted on the cylinder 15, and at its outer end said sleeve has a radially extending flange-like head 51 in which radial slots 52 are found on opposite sides of the cylinder 15. On the outer face of the disk 51 there are mounted two plates 53 on opposite sides of the tube of glass when in place, and both are vertically slidable to wards or away from each other in two radial guideways 54 and carry four binding posts 55, two on each side of the center, and the inner ends of the binding posts project towards the glass article when in place.- An electric wire 56 connects the inner ends of the two binding posts, and the wire 57 the inner ends of the other two binding posts. A conductor 58 connects the two pairs of binding posts, while a conductor 59 leads to, and a wire 60 leads from the binding posts, as appears in Fig. 4. These Wires 56 and 57 are moved towards and away from the glass article by two levers 62, shown in Fig. 3, that are fulcrumed by the pins 63 to outwardly extending ears 64 on the cylinder 15. The actuating ends of these levers 62 extend through slots 52 in the disk 51 and through holes at 65 in the sliding plates 53. The actuated ends of said lever are curved outwardly from the cylinder 15 and havein each a curved slot 66 in which a pin 67 extends from the cars 68 on a sliding sleeve 69 that surrounds the cylinder 15 and is slidable longitudinally thereof by a hand-lever 70 that is fulcrumed at its lower end to a post 71. A ring 169 formed oftwo semicircular parts connected by the bolts 1'70 fit loosely in an annular groove in the sleeve 69. The lever 70 just below the cylinder 15 is divided into two semicircular arms. that unite again above said cylinder so that said two arms loosely surround the ring 169 and at each side are pivoted to the ring 169 by pins 72.

Themotor 24 is mounted on a post 73, and from it conductors 74 and 75 extend to the posts mounted on the base 10 upon suitable insulation 78, and carry;

.ing another section.

the two brushes 7 9 and 80 that contact with the two rings 81 and 82 that surround the sleeve 83 on the cylinder 15 and are insulated therefromby insulation 84, which is held in place by an annular nut 85. The current from the ring 82 is transmitted through a wire 86 embedded in insulation 87 at one side of the cylinder 15 to the conductor 59. The current passes from the other conductor to a wire 87 in an insulation strip 88 at the opposite side of the cylinder 15 and to "the ring 81.

In operation, the tube of glass is inserted :into the machinelongitudinally, and before such insulation the holders 37 are moved radially outward to their limit, andlikewise the block-s53 and wires 56 at the other end of the machine. After the glass is inserted, the hand 'lever 42 is operated to hold it in place, so the glass tube is held stationary. Then the lever is thrown to the left, as appears in Fig. 3, which forcibly moves the cracking off wires 56 and 57 into engagement with the glass, and since the means for holding the cracking-off -wires are revoluhle with the cylinder 15, said wires are rapidly carried around the glass tube, so that their heat will sever the glass. When this is done, the lever 70 is thrown to the right, which moves said cracking-off wires 56 and 57 away from each'other, and the lever 42 is ,pulled outward for separating the clamps 37, and then the glass tube is moved slidably through the cylinder 15 'for' sever- During the operation of the de- Vice, the cylinder 15 continues to rotate.
